Grounding the switch

WARNING:
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.
The power input end of the switch has a noise filter, whose central ground is directly
connected to the chassis to form the chassis ground (commonly known as PGND). You
must securely connect this chassis ground to the earth so the faradism and leakage
electricity can be safely released to the earth to minimize EMI susceptibility of the switch.
You can ground a switch by using a grounding strip at the installation site or the AC power
cord connected to the switch.
